Researchers from the United States have developed an efficient way to produce hydrogen gas from urine - of course it became one of alternative sources of fuel for future cars, but also a way to memperdayagunakan waste generated by humans. The use of hydrogen gas to fuel cars has become the alternative fuel use increases, this is caused by the hydrogen gas use traditional exhaust gas produced does not pollute the lingkuangan due out only water vapor.

However, one of the obstacles faced is the lack of a source of hydrogen gas is cheap and easy to update. Gerardine Botte of Ohio University has found a possible answer to these problems, by using the electrolysis process approach he managed to produce hydrogen gas from urine, one of the most abundant waste in the earth and of course urine is a source for free so it can cut the cost of hydrogen gas production.

Botte says that this idea came to him several years ago when she attended a conference of fuel, then he discusses how to change the water resources become a source of clean energy resources. "I hope we can turn water into a source of environmentally friendly energy", he said. He also began thinking about the search for sources of waste that can be used as a source to produce hydrogen gas.

Content of urine is primarily urea, which urea has four hydrogen atoms per molecule, hydrogen iktan with N in urea ataom weaker than hydrogen bonds with O atoms in the water. Botte then decided to use electrolysis to break the urea molecule by using nickel-based electrode is selective and efficient to oxidize urea. To break the urea molecule is required voltages for 0.37 volts where the voltage is still lower than that required for electrolyzing water is about 1.23 volts.

During the process of urea teradsorbsi on nickel electrodes, which then flow the electrons which then decompose urea molecules. Pure hydrogen gas is formed at the cathode, nitrogen gas and a little oxygen and hydrogen gases are formed in the anode. Carbon dioxide gas is also produced during electrolysis, but this gas will not mix with the gas generated at the anode and cathode due to this gas reacts with KOH to form potassium carbonate. "It takes time for us to use human rine as an experiment so we can mempubilkasikan our research," says Botte.

According to Botte, existing processes to separate the urine from the water current is very expensive and inefficient. Urine is generally hydrolyzed into amonik before detaching keudara as ammonia gas. The formation of this gas will form ammonium sulfate and nitral particles in the air, where both of these substances can cause various problems for human health such as asthma, bronchitis, and premature death.

Group researchers have spent much time studying the electrolysis system that will be used including the study of computational reaction mechanisms. Botte believe that this technology will be able to be made in a large scale to produce hydrogen gas. "One of the obstacles that hinder the process is the amount of salt contained in urine source," says Botte.

Bruce Logan, an energy expert and director of waste Pennsylvania State University's H2E Center and Engineering Environmental Institute give applause to the Botte who have contributed to the alternative hydrogen production without breaking the water molecules. After all he gave a statement that the urea suatau more quickly converted into ammonia by using the bacteria, it is of course a limitation of research conducted by Botte. But Logan feels that Botte very good idea to figure out how to process the waste of our urine to produce not only hydrogen but also to generate other sources such as sources of fertilizer phosphorus menginggat future as well as phosphorus crude oil could become a rare item and we must think of ways to mericycle phosphorus for future purposes.
